fix(traffic): restore quota-disabled inbounds when their traffic is reset (#6962)

An inbound switched off by its own traffic cap came back on the periodic reset, but the admin per-inbound reset and Reset All Traffic only zeroed the counters. After that nothing could tell it from a hand-disabled inbound, so it stayed off with every client on it. Both admin resets now re-enable the inbounds their cap switched off, using the predicate the periodic job used, now in the service next to disableInvalidInbounds; expired and hand-disabled inbounds stay off.
